RotaCut

What it is

RotaCut is an inline macerator and heavy-material separator in one compact unit. It cuts fibrous and coarse material in pumped liquids while trapping stones and metallic objects before they reach pumps, valves and other downstream equipment.

How it works

As the substrate flows through the housing, heavy objects settle into the separator. Fibres and soft solids pass across a cutting screen where rotating blades produce a more homogeneous, pumpable suspension. Automatic Cut Control (ACC) maintains blade-to-screen contact; PCU monitoring and DRS foreign-matter removal are available for specified configurations.

Where it is used

Biogas slurry and digestate circuits; liquid manure; wastewater and sludge; food-industry liquid waste; protection before pumps and heat exchangers.

Key advantages

  • Cutting and heavy-material separation in one process step.
  • ACC blade-pressure control for consistent cutting with less manual adjustment.
  • Broad range of RC, RCQ and RCX configurations, including Inline and DRS options.

Technical characteristics

Electric-drive models in the supplied technical table range up to 1,200 m³/h (RCX-68); actual throughput depends on dry matter content. Other model-specific limits differ. The individual variants are compared in the table below.
